By synthesizing derivatives of a trans-1,2-diaminocyclohexane precursor, three new functionalized porous organic cages were prepared with different chemical functionalities on the cage periphery. The introduction of twelve methyl groups (CC16) resulted in
Influence of the metal and chiral diamine on metal(II)salen catalysed, asymmetric synthesis of α-methyl α-amino acids

The influence of the metal ion and chiral diamine used to form a metal(salen) complex on the catalytic activity of the complex in the asymmetric benzylation of an alanine enolate was investigated. Only metal ions which could form square-planar complexes g

(3R,4R,5R,6R)-3,6-Diphenyl-N,N′-bis[(S)-1-phenylethyl]octa-1, 7-diene-4,5-diamine, by treatment with organolithium reagents RLi in controlled experimental conditions, underwent rearrangement and/or substitution of one or two branched allyl(s) by the R group(s). Hence, this diene behaves as a masked form of the chiral glyoxal diimine from that it is prepared, allowing the preparation of C1-symmetric 1,2-disubstituted 1,2-diamines, which are generally not available by the direct addition of organometallic reagents to the diimine, and C2-symmetric 1,2-diamines with good diastereoselectivities.
The stereoselective synthesis of functionalized vicinal diamine systems by the double allylation reactions of "protected" 1,2-bis-imine precursors
Neumann, William L.,Rogic, Milorad M.,Jeffrey Dunn

A diastereoselective synthesis of vicinal diamines via the reactions of allylic Grignard reagents with readily available "protected" 1,2-bisimines has been developed. This method has been extended to preparing optically pure diamines by the use of chiral
